Business signage in South Florida requires specific permits regardless of size, illumination type, or mounting method. Local zoning ordinances control sign dimensions, illumination, placement, and even color in some historic districts. Unpermitted signs result in code enforcement action and removal orders.
This guide details sign permit requirements for commercial signs across Miami-Dade, Broward, and Palm Beach Counties in 2026.
TYPES OF COMMERCIAL SIGNS REQUIRING PERMITS
Permits are required for wall-mounted signs (channel letters, cabinet signs, dimensional letters), monument signs (free-standing ground-mounted), pole signs (where allowed by zoning), projecting signs (perpendicular to building face), pylon signs (multi-tenant identification), illuminated signs (interior-illuminated, halo-illuminated, internally lit cabinets), digital and LED message boards (where permitted), window signs (often regulated by coverage percentage), and temporary signs and banners. Each sign type triggers different review criteria and fee structures.
ZONING AND CODE COMPLIANCE
Sign permits require zoning compliance verification: maximum sign area calculated as percentage of building facade or store frontage, maximum height for monument and pole signs, setback requirements from property lines and right-of-way, illumination restrictions (lumens output, hours of operation, dark sky compliance), prohibition of certain sign types in residential-adjacent areas, and color and material restrictions in historic districts. Sign codes vary significantly between municipalities; each location requires individual review.
ELECTRICAL REQUIREMENTS FOR ILLUMINATED SIGNS
Illuminated signs require separate electrical permits in addition to the sign permit: dedicated circuit from main service panel, weatherproof disconnect within sight of the sign, GFCI protection where applicable, listed sign components (UL 48 for sign equipment), proper grounding and bonding, and inspection of completed electrical work before energizing. Older signs converting to LED illumination may require electrical permit even when not changing sign size or location.
TYPICAL PERMIT COSTS
Sign permits in Miami-Dade County typically run $200 to $800 per sign depending on size and type. Broward County runs $175 to $700. Palm Beach County runs $250 to $900. Electrical permits for illuminated signs add $150 to $400 each. Permits in historic districts (Coral Gables, Miami Beach, Palm Beach) cost more due to additional design review. Variance applications when sign exceeds zoning limits add $500 to $2,500 in fees plus 8 to 16 weeks of timeline.
APPROVAL TIMELINES
Sign permits typically process within 2 to 6 weeks in Miami-Dade County for compliant signs, 2 to 5 weeks in Broward County, and 3 to 7 weeks in Palm Beach County. Signs requiring design review by historic preservation boards add 4 to 12 weeks. Variances for non-compliant sign proposals add 8 to 24 weeks for zoning board hearing process. Mall-located signs require landlord approval in addition to municipal permits, adding 2 to 6 weeks.
STRUCTURAL ENGINEERING
Larger signs require structural engineering: monument signs over 6 feet require engineered foundation design, wall signs over a defined size or weight require attachment engineering, projecting signs require structural analysis, and pole signs require foundation and pole engineering. South Florida hurricane wind loads add structural requirements: HVHZ wind loads of 175 mph apply to all signs, signs must remain attached during hurricane events without becoming projectiles, and structural certification by Florida-licensed engineer required.
TENANT IDENTIFICATION SIGN PROGRAMS
Multi-tenant retail centers, office buildings, and medical office complexes typically have approved master sign programs governing tenant signage: standardized dimensions and placement, approved illumination types and lumens output, approved color palettes and font styles, common materials and mounting methods, and unified design aesthetic. Tenant signs must comply with the master program even when general zoning would permit larger or different signs.
TEMPORARY AND BANNER SIGN PERMITS
Temporary signs (grand opening, sales events, construction site identification) require permits in most South Florida jurisdictions: typical permit duration 30 to 90 days, maximum size limits significantly less than permanent signs, prohibition on multiple consecutive temporary permits, separate review for political signs in election seasons, and prohibition in residential zones except for property sales. Banner signs in particular face strict regulation and short permit durations.
